I'll take that bait: I think there's a bug in the wiring checks.

Simplest way to see is to compile e.g. RadioCountToLeds for tinynode
(make tinynode).
you will have the warning " interface XE1205PhyP.SplitControl
underwired", even though it is wired (as can be seen   either by
checking the app.c, or going through the code:

tos/platforms/tinynode/ActiveMessageC.nc
 tos/chips/xe1205/XE1205ActiveMessageC.nc
tos/chips/xe1205/XE1205SendReceiveP.nc
tos/chips/xe1205/XE1205Phy{C,P}.nc
